R help - Sep 2011 - randomForest - NaN in %IncMSE

Hi

I am having a problem using varImpPlot in randomForest.  I get the error
message "Error in plot.window(xlim = xlim, ylim = ylim, log = "")
:   need
finite 'xlim' values"

When print $importance, several variables have NaN under %IncMSE.   There
are no NaNs in the original data.  Can someone help me figure out what is
happening here?

Thanks!

You are not giving anyone much to go on.  Please read the posting guide and see
how to ask your question in a way that's easier for others to answer.  At
the _very_ least, show what commands you used, what your data looks like, etc.
